Q&A and Customer Reviews


1.Is the 6xHis-SUMO tag retained or is it cleaved after your expression?
2.Has this molecule been shown to bind to anti-HLA-E and anti-HLA-ABC (pan class I) antibodies?

Thanks for your inquiry.1. If you needs to remove the tag, please communicate with us in advance, otherwise, we won't remove the tag. Not all protein tags can be removed as some proteins will be very unstable after tag removal. If we succeed in removing the tag, we will charge for extra cost.
If we fail in removing the tag, we won’t charge for any extra cost, and remark this information in datasheet as follows “Note: The laboratory determined that the Tag on your protein could not be removed with standard laboratory procedures. Your protein is being supplied with the Tag intact.”
Generally, the delivery time will be extended for 2-3 days.
2. This protein can bind to anti-HLA-E and anti-HLA-ABC (pan class I) antibodies in theory, but we haven't performed relevant validation. It is suggested that antibodies and antigens are derived from the same recombinant expression system, because the conformation of proteins expressed by different recombinant expression systems will be different, which may lead to difference in recognition.

I hope this email finds you well. I am interested in this protein but they would like to know more information regarding its biological activity. Is this information available for me to share?

Very nice to receive your inquiry.
We haven't tested the biological activity of this protein. The protein we provide is the complete extracellular domain purified under mild conditions which should have activity in theory.
This protein has been delivered for many times. Any more questions, feel free to contact us.
